Ib lub cav asynchronous puas muaj hluav taws xob?
Muaj ntau tus neeg nyeem tau tshaj tawm tias lub xeev ntawm kev tsim hluav taws xob ntawm asynchronous motors, yog hais tias nws yuav tsum to taub, nws tsis yooj yim: thaum qhov kev taw qhia ntawm lub rotor tam sim no yog hloov, nws ua ib lub xeev ntawm lub zog tiam. Tab sis thaum koj xav txog nws zoo zoo, koj ib txwm xav tias nws tsis meej: qhov feem theem ntawm tus stator hloov tam sim no tom qab lub rotor tam sim no puas tau? Puas muaj cov generator asynchronous? Tus kws sau ntawv nrog ib tus qauv nrov thiab piav qhia qhov tseeb thiab tau ua tiav zoo.
Ib lub tshuab hluav taws xob yog ib lub tshuab uas hloov cov tshuab hluav taws xob rau hauv hluav taws xob. Uas yog hais, los ntawm txoj kev tig ib lub rotor ntawm lub cev muaj zog nrog lub zog mov (turbine, diesel, turbine, thiab lwm yam.), Hluav taws xob muaj peev xwm yuav ua tau generated, uas yog, lub cim hluav taws xob.
Txhua lub cav yog rov qab thiab siv tau los ua lub tshuab fais fab thiab ua ib lub tshuab hluav taws xob. Asynous motors yog tsis muaj kev zam, tab sis lawv muaj lawv cov kev xyuam xim.
Tshwj xeeb ntawm asynchronous generator
Ua ntej saib li cas lwm cov tshuab hluav taws xob tsim hluav taws xob?
(1) DC generator
Tus stator ntawm DC generator yog ib qho sib nqus ncej, thiab lub rotor yog ib qhov chaw sib tw, raws li qhia hauv daim duab a.
Thaum lub zeeg yuav tsav lub rotor tig, tig qhov kev sib tw ua kom muaj kev sib txuas ntawm lub tshuab hluav taws xob los ntawm tus stator magnetic field, thiab DC voltage yog tau los ntawm cov khoom sib dhos thiab txhuam.
(2) Synchronous generator
Tus stator ntawm tus synchronous generator yog ib qho peb theem, thiab lub rotor yog ib tus pas hlau, raws li qhia hauv daim duab b.
Thaum lub zeeg yuav tsav lub rotor tig, tig peb theem theem ntawm tus stator txiav lub rotor magnetic field los ua kom muaj kev sib raug zoo electromotive quab yuam, ua li no tawm ib theem rau peb theem.
(3) Feem ntau ntawm cov qauv siv hluav taws xob (generators) thiab cov twj generator (synchronous generators)
1) Tag nrho lawv muaj tsau hlau nplua nuj;
2) Nyob hauv kev tsav tsheb ntawm tus cwj pwm txav, cov cua ntsuag tau txiav cov hlau nplaum ntawm lub zog thiab "xa" hluav taws xob los ntawm qhov kawg.
(4) Kev tsim tawm ntawm lub tshuab hluav taws xob asynchronous
Lub stator ntawm lub tshuab asynchronous yog ib theem peb theem, thiab lub rotor yog luv luv-winding winding thiab tsis muaj magnetic teb nws tus kheej. Yog li ntawd, lub cav asynchronous tsuas yog powered los ntawm tus thawj mov. Txawm hais tias, nyob rau hauv kev tshawb xav, kev siv cov residual magnetism kuj ua tau hluav taws xob, tab sis nws tsis muaj qhov tseem ceeb.
Hauv kev txiav txim rau lub tshuab asynchronous los ua hluav taws xob, nws yog thawj zaug tsim nyog los tsim kom muaj ib qho chaw magnetic. Txawm li cas los xij, ib qho asynchronous engine generates ib qhov chaw magnetic tom qab uas muaj peb theem tam sim no dhau los ntawm peb-theem cua ntawm lub stator. Uas yog hais, kom tau ib lub teb chaw magnetic, lub asynchronous winding ntawm lub cav asynchronous yuav tsum tau txuas nrog rau cov qauv peb theem, raws li muaj nyob hauv daim duab c. Yog tsis muaj kev ntseeg tias nyob rau hauv cov ntaub ntawv no nws yuav ua hauj lwm raws li ib qho asynchronous engine. Txawm li cas los xij, yog hais tias tus zais zis siv los tsav lub rotor mus rau ntau tshaj qhov sib npaug ntawm qhov sib npaug, nws yuav yog ib qho generator asynchronous.
Yog li, asynchronous motors tsis tau tsim hluav taws xob ntawm nws tus kheej los ntawm kos, uas yog nws cov particularity.
